This invention relates to the magazines of typographical machines such as those known under the trade mark linotype, and particularly to machines in which a plurality of superposed short magazine sections are adjusted relatively to the assembler and to a lesser number of stationary upper magazme sections which serve to guide the matrices from the magazine entrance to the respective channels in the short sections;

In certain of thesev machines the short magazines (known as side or auxiliary magazines and here, for convenience, regarded as four in number) are located at one side of the main magazines and when adjusted columnwise, two of them are brought into operative relationship with the assembler and the upper short sections, while the upper ends of the other magazines are left exposed and uncovered, either above or below, or perhaps bothvabove' and below, the short upper sections.

- Owing to the'fact that't'woof the magazines are usually much less frequently used than are the others, a considerable amount of dust is liable to enter the exposed ends an cause trouble.

The object of the present invention is to provide means which shall ensure the automatic closing of the upper ends of those of the magazines which are not for the time being required for use, this being effected during the columnwise movement of the magazines.

With said object in view, the invention provides shields which automatically cover or close the exposed upper ends of those of the magazines which for the time being are not in use.

The invention will now be more particularly describedby reference to the accompanying drawings which illustrate a constructional form of the invention as embodied in a machine having four side or auxiliary magazines adapted to selectively cooperate with two upper short sections.

In the drawings Figure 1 is a diagrammatic side view of the pertinent parts of a machine embodying 501,835, and in GreatBritai-n August 1930.

of arod 2, fast to the shield, in lugs 3, 3, at-

tached to the sides of the underlying frame 4 of the upper short magazine section 5. 7

When, with this arrangement, the adjustable magazine column 6 is in its lowermost position, as shown'in Figure2, the shield 1 overlies the upper part of said column, and is resiliently held in that position bya spring 7 which encircles the rod 2 and bears at its respectively opposite ends upon the said shield and the top of the short magazine section 5. By the provision ofthe spring 7,

the upper shield 1 is free to yield and cover the open ends of the short magazine sections 1 of the adjustable column 6, as indicated in Figure 1, when said column is raised from a lower position; and when the. column is brought into its lowermost position the shield 1, by this same spring, is automatically turned down over the top of the column, as shown in Figure 2. I l

For facilitating the removal of the adjustable magazine sections from the machine, provision is made for readily detaching the shield 1. Such provision may be conveniently attained by securing the lug 3 to the frame 4 with a capacity for sidewisemove- Inent out of engaging relationship with the respective end of the rod 2. For this purpose the lug 3 is held to the frame 4 by a screw 8 between whose head and the said lug, is interposed a compression spring 9 which normally holds thelug on the end of the rod 2, but which allows the lug to be drawn rightwards todisengage it from that rod to enable the shield 1 to be freely, removed. The lug 3a is prevented from turning on the screw 8 by dowel pins 10 fast on the lug 3 and loosely engaging the frame4, or vice versa. Only one PATENT OFFICE I of the lugs 3, '3 need be thus movable, hence,

' the lug 3 will usually be rigidly attached to the frame 4.

The dust cover or shield 11 at the under side of the short upper sections 5,.5 is loosely pivoted on a rod 12, extending-across adjacent parts of the machine frame, and this shield, by its own weight alone, or aided by a spring, assumes aposition closely overlying the upper ends of those of the movable magazines sections which, at the time, are below the upper sections 5, 5 as is clearly evident from Figure 2. If desired, the pivot rod 12, may be removable from the machine, for enabling the shield 11 to be easily detached when it is desired to remove the magazines from the machine. To this end the rod may, as shown in the drawings, be provided with a knurled head 12 and be thread-ed, as at 12 into one side of the frame 4.

Although the foregoing description deals mainly with the application of the invention to the side or auxiliary magazines, said invention can, with considerable advantage, be

equally well applied to the main magazines, in which arrangement the lugs supporting the upper shield would be mounted on what is known as the back bracket.

Furthermore, it is to be understood that' other variations or modifications can be carried out without departing from the essential features of the invention; for instance,

instead of the shield 1 being acted upon by a spring, it may be relied upon to close the ends of the magazines, by its own weight or by its own weight supplemented by an additional weight.

Having described my invention, I declare that what claim and desire to secure by Letters Patent is I 1. In a typographical composing machine, the combination with an adjustable COlumn of magazines, of a shield carried on a stationary part of the machine and movable automatically, by the raising of the magazine column, to cover the upper ends of those of the magazines which are brought into inoperative position by such raising.

V 2. In a typographical composing machine, the combination with an adjustable column of magazines, of a shield pivotally mounted on a stationary part of the machine so as to overlie the topmost magazine when the latter is 1n operative position, and movable on its pivot, by the raising of the magazine column, through engagement therewith to a positionin which it covers the upper ends of those of the magazines which are brought into inoperative position by such raising.

3. In a typographical composing machine, the combination with an adjustable column of magazines, of a shield adapted to overlie the topmost, magazine when the latter is in operative position and to cover the upper ends of magazlnes raised to inoperative posileast one of the lugs to the machine frame with a capacity for disengagement from the shield.
